Prologue
It's been 10 years since the JS incident. Vivio, now a 16-year-old teenager, chose to drop out of school and join the TSAB. Her mothers had a heart attack when Vivio had been critically injured during a mission over the summer.
She refused to back down to her mothers, but her own girlfriend finally got her on a guilt trip when she was 15. Ever since then, she rededicated herself to her studies, determined to prove that she already knew everything she needed to know to enlist in the military.
However, she's determined now that Einhart was graduating for the 2 of them to spend plenty of alone time together. She had the perfect plan. She convinced Fate to buy 2 one way tickets behind Nanoha's back. That managed to go unnoticed until Nanoha came home early and checked the mail. Needless to say, she chased both Fate and Vivio trying to shoot them with a Starlight Breaker.
After a couple of days, Nanoha finally calmed down enough for Vivio to explain why she did that. Eventually, she was grounded and not allowed to go anywhere without her approval which meant that her time with Einhart was either supervised or shortened considerably. It's been 3 months since then and Vivio had just returned from a month long mission.
